NIST SP 800-171 Compliance Services
110 controls. 14 families. One score your prime already knows.
NIST SP 800-171 is the underlying standard for protecting Controlled Unclassified Information across the entire DoD supply chain — and the foundation that CMMC Level 2 is built on. Every contractor handling CUI has a SPRS score against it. Most don’t know what theirs actually is, can’t defend the documentation behind it, and learn the score is wrong only when a contract doesn’t renew.
Intelecis is headquartered in Fullerton, CA, and guides defense contractors across all 110 NIST 800-171 controls — from gap assessment and SPRS scoring to a defensible System Security Plan, every gap closed, and the same standard ready for your C3PAO assessment when CMMC requires it.

NIST 800-171 — The Risk
A SPRS score that can’t survive a contracting officer’s question.
NIST 800-171 has been required on DoD contracts since DFARS 252.204-7012 took effect — but the rule that turned it from paperwork into a sharp edge was DFARS 252.204-7019, which made your SPRS score visible to every prime and contracting officer who looks. Most contractors filed a score to keep bidding. Most of those scores were estimated, not assessed. And under the DOJ’s Civil Cyber-Fraud Initiative, the gap between an estimated score and an assessed one is the difference between routine compliance and a False Claims Act case.
The DFARS CMMC Final Rule took effect November 10, 2025. Phase 1 is live. Phase 2 in November 2026 requires C3PAO assessment for most Level 2 contracts — and that assessment is graded against the same NIST 800-171 controls. The shops that got their 800-171 program right the first time walk into CMMC with the work already done.
Could you produce, today, the documented evidence behind every score in your SPRS submission?
DFARS 252.204-7019 requires a current self-assessment on file — and DOJ FCA cases have targeted exactly this gap.
Does your System Security Plan describe your actual environment, or a template environment you don’t operate?
Generic SSPs are the single most common finding in failed CMMC mock assessments.
If a control is marked POA&M, can you show the closure date, owner, and progress evidence?
Aging POA&M items without traceable remediation invalidate the score they support.
Most contractors call us after the SPRS portal arrived in a conversation they didn’t expect.
A contracting officer asked. A prime ran a supplier review. A new opportunity required a posted score and the existing one wouldn’t hold up. NIST 800-171 isn’t a paperwork exercise — it’s the standard by which your defensibility is judged. Getting it right once is cheaper than getting it wrong twice.
How It Works
From estimated score to defensible standard.
Three phases. One SoCal-based consultant. No handoffs to offshore teams or junior staff. The same expert manages your NIST 800-171 program from kickoff through SPRS submission, ongoing maintenance, and the moment your CMMC C3PAO assessor walks in — built so the work you do for 800-171 carries straight through to CMMC Level 2 without doing any of it twice.
Gap Assessment & SPRS Scoring
We evaluate your environment against all 110 NIST 800-171 controls and the 320 assessment objectives in NIST SP 800-171A, document where CUI lives, calculate your accurate SPRS score using the official DoD scoring methodology, and produce a defensible record of the assessment that will hold up under scrutiny. We develop your System Security Plan (SSP) and Plan of Action & Milestones (POA&M) — written to your actual environment, not a template — and guide you through submitting your score to the SPRS portal with the supporting documentation in place.
Remediation & Control Implementation
We help implement the controls needed to close every gap across the 14 control families — access management, MFA, audit logging, configuration management, incident response planning, media protection, system and information integrity, and the rest. Every implementation is documented in the SSP and traceable to the corresponding 800-171 requirement and its 800-171A assessment objectives. A gap report you have to act on yourself isn’t compliance — it’s homework. We do the work alongside your team so when CMMC time comes, there’s nothing outstanding.
SPRS Maintenance & CMMC Readiness
We monitor your posture continuously — so annual SPRS updates, DFARS clause flow-downs, and policy refreshes never catch you off guard. When CMMC Phase 2 requires a C3PAO assessment for a contract you hold, your 800-171 program is already the foundation: same 110 controls, same SSP, same evidence packages, ready to walk through assessment day without re-doing the work.

The Standard
110 controls. 14 families. One defensible record.
NIST 800-171 organizes 110 security requirements into 14 control families. NIST 800-171A defines 320 assessment objectives across them. NIST 800-172 adds enhanced requirements for high-value CUI. Most contractors interact with the standard through SPRS scoring — which is exactly where the defensibility gap shows up.
Standard
14
Control Families
The 14 families cover the full lifecycle of CUI in your environment — from who can access it, to how it’s transmitted, to what happens when something goes wrong.
- Access Control · Awareness & Training
- Audit & Accountability · Configuration Management
- Identification & Authentication · Incident Response
- Maintenance · Media Protection · Personnel Security
- Physical Protection · Risk Assessment
- Security Assessment · System & Communications Protection
- System & Information Integrity
Where the Score Lives
110
Security Requirements
Each of the 110 requirements has multiple assessment objectives defined in NIST 800-171A — the methodology that DoD assessors and C3PAOs use to determine whether the control is actually met. A control marked “implemented” without the objectives evidenced is the most common gap we find on first review.
- Each control scored fully met (+0), partially met (-3 or -5), or not met
- Maximum score: 110. Minimum score: -203
- POA&M items reduce score until closed within deadline
- Score visible in SPRS to all primes and contracting officers
Enhanced
172
NIST SP 800-172
For contractors supporting the DoD’s most sensitive programs — advanced systems, classified research, and critical national security work. 800-172 layers additional protections on top of 800-171 and aligns to CMMC Level 3.
- Designed to defend against advanced persistent threats
- Government-led DCMA assessment for CMMC Level 3
- Triennial reassessment cycle
NIST 800-171 — By the Numbers
One standard. Every defense contract handling CUI. Visible to every prime.
NIST 800-171 isn’t a sector-specific framework — it’s the standard the DoD uses to evaluate whether you can be trusted with Controlled Unclassified Information. Your SPRS score is the headline. The 110 controls behind it are the substance. The documentation tying them together is what survives an assessment.

Why Intelecis
Built around security. Not bolted onto it.
Most IT companies added NIST 800-171 to their service menu when DFARS started requiring it. Intelecis built its practice around advanced cybersecurity — including classified military and intelligence environments — long before DFARS made the standard contractual. We’re based in Fullerton, CA, and we work with defense contractors across all 110 800-171 controls every week.
Military Security Foundation
Our team brings classified military intelligence experience to every engagement. NSA-accredited for Cyber Incident Response Assistance — one of the only firms in Southern California that can make that claim. This isn’t a marketing credential. It’s the difference between a SPRS score that holds up and one that becomes a liability.
We Help Close Gaps — Not Just Name Them
A gap report you have to act on yourself isn’t compliance — it’s homework that sits on someone’s desk. Intelecis helps implement every missing control, policy, and documentation requirement alongside your team. By the time you submit to SPRS, the score is real, the evidence is in place, and the same work is ready for CMMC.
One Consultant, Start to Finish
No ticketing systems. No rotating junior staff. No explaining yourself to someone new every month. A dedicated Intelecis consultant manages your 800-171 program from kickoff through SPRS submission and every annual update after — the same expert, the same relationship, throughout.
SSPs Written to Your Environment
System Security Plans, POA&Ms, policies, and evidence packages — all written to the systems and processes you actually operate, not a template environment from a vendor library. When an assessor asks how a specific control is implemented, the answer is in the document and matches what they see on the network.
Compliance That Doesn’t Expire
800-171 requires annual SPRS updates, current SSPs, and POA&M closure within deadlines. Most contractors pass once and drift. Intelecis monitors your posture continuously — so your score stays defensible, your evidence stays current, and CMMC time isn’t a fire drill.
800-171 → CMMC Without Doing It Twice
CMMC Level 2 is graded against the same 110 NIST 800-171 controls. Done right, your 800-171 program is your CMMC program — same SSP, same POA&M, same evidence. We build for both from day one, so when Phase 2 requires C3PAO assessment, the work is already done and you walk in ready.
Who NIST 800-171 Applies To
If CUI touches your systems, this is you.
NIST 800-171 applies wherever Controlled Unclassified Information lives outside the federal government — across every tier of the defense supply chain, and across industries far broader than most contractors realize.
🛩️
Defense Primes & Subs
Aerospace, defense electronics, weapons systems, and DoD program supply chains at every tier — wherever DFARS 252.204-7012 flows down.
Without 800-171: your SPRS score won’t qualify you for the next contract or option period.
⚙️
Manufacturers & Component Suppliers
Precision machining, metals, fabrication, components, and assemblies — anywhere a DoD drawing or specification with CUI markings enters the shop.
Without 800-171: the drawings stop coming, the blanket POs stop renewing.
🖥️
Defense IT, MSPs & Technology Firms
Service providers, technology vendors, and platform firms supporting defense customers — themselves in scope wherever they touch client CUI.
Without 800-171: defense clients are required to move to certified providers.
📋
Professional Services Handling CUI
Engineering consultants, legal, accounting, government relations, and program-support firms working on DoD engagements that carry CUI.
Without 800-171: handling CUI without compliant systems creates False Claims Act exposure for the firm and the signers.
🎓
Research Institutions & Universities
Academic and research organizations conducting DoD-funded research that involves CUI — whether classified-adjacent technology, fundamental research with restrictions, or sponsored program data.
Without 800-171: research grants pause or move to compliant institutions.
🏛️
Federal Civil Agency Contractors
800-171 reaches beyond the DoD — agencies including GSA, NASA, DHS, and others flow CUI protections through similar contract clauses to their contractor base.
Without 800-171: civil-agency CUI requirements catch contractors who assumed they were out of scope.
Common Questions
Answered plainly.
No acronym soup. No compliance theatre. Direct answers to what defense contractors actually ask about NIST 800-171 — and what it means for your SPRS score and your CMMC readiness.
What's the difference between NIST 800-171 and CMMC?
800-171 is the standard. CMMC is the verification program built on top of it. NIST 800-171 defines what to do — 110 security requirements across 14 control families. CMMC defines who confirms you did it — DoD assessors at Level 1, your own attestation at Level 2 self-assessment, and a C3PAO third-party assessor at Level 2 certification. The 110 controls are the same. The difference is how rigorously someone outside your company verifies them.
If we've already implemented 800-171, why do we still need CMMC?
Because self-attestation under DFARS 252.204-7019 has been the system since 2020, and the DoD found too many SPRS scores didn’t survive scrutiny. CMMC was built to add independent verification — a C3PAO confirms what your SPRS score claims. If your 800-171 program is genuinely complete and well-documented, CMMC adds an audit step but no new substantive work. If your SPRS score is estimated rather than assessed, CMMC reveals the gap.
How is the SPRS score calculated?
Every contractor starts at 110 points. Each of the 110 controls is either fully met (no deduction), partially met (subtract 1, 3, or 5 points depending on the control’s weight), or not met (full deduction). The math runs all the way down to a theoretical minimum of -203. The score is calculated using DoD’s official scoring methodology and posted in the SPRS portal, where primes and contracting officers can see it. The score by itself isn’t compliance — the documented assessment behind it is what makes the score defensible.
What does an actually defensible SSP look like?
A System Security Plan that describes your actual environment — the systems you operate, the data flows you process, the people with access — control by control, with enough specificity that an assessor reading it could walk into your office and recognize the network they’re looking at. Template SSPs that describe a generic environment fail this test. The single most common finding in failed CMMC mock assessments is “SSP doesn’t match the environment.” We write SSPs to the system you actually run, not the system the template imagined.
How long does NIST 800-171 implementation take?
For most contractors, 3–8 months from gap assessment to a defensible SPRS score and complete SSP. Smaller, well-managed environments with mature IT practices land at the shorter end. Larger organizations, or environments with significant legacy infrastructure, take longer because remediating older systems takes time. The work compounds: a 800-171 program done thoroughly is also a CMMC Level 2 program, which means the same months of work answer two requirements at once.
What is the False Claims Act risk on an inaccurate SPRS score?
Under the DOJ’s Civil Cyber-Fraud Initiative, contractors who submit an inaccurate SPRS score can be prosecuted under the False Claims Act, which carries treble damages — 3× the contract value — plus per-claim penalties. This isn’t theoretical. The DOJ has already settled multiple cases. The exposure attaches personally to the executive who signs the attestation, not just to the company. A score that isn’t based on a defensible, documented assessment puts that signer’s name on the line. The fastest way to reduce that exposure is a real assessment with real evidence behind it.
